# Applied KJS (AE2 \u00d7 KubeJS Bridge)<\/p>\n
> A powerful AE2 \u2194 KubeJS bridge for modpack developers that adds scriptable AE2 recipes, network monitoring, storage\/crafting events, device inspection, and optional ME crafting job automation.<\/p>\n
**Applied KJS** is a bridge mod for **Applied Energistics 2 (AE2)** and **KubeJS** that gives modpack developers deep, scriptable access to AE2 systems without writing a dedicated Java addon for every pack.<\/p>\n
If you want to build AE2-focused progression, automation, diagnostics, alerts, or recipe overhauls in KubeJS, this mod is built for that workflow.<\/p>\n
The **wiki page** can be found **~~here~~**! (coming soon, you can view my pull request here. And you can view the wiki page’s raw code here.)<\/p>\n
***<\/p>\n
## What this mod adds<\/p>\n
### \u2705 AE2 recipe scripting helpers for KubeJS<\/p>\n
Create and manage AE2 recipe JSON from scripts, including helpers for common AE2 recipe types such as:<\/p>\n
* Charger recipes
\n* Inscriber recipes (including press-style setups)
\n* Transform recipes
\n* Entropy recipes (heat\/cool behavior)
\n* Matter Cannon ammo behavior entries<\/p>\n
Also includes utilities to help with:<\/p>\n
* Building recipe JSON safely
\n* Validating and stringifying recipe JSON
\n* Adding\/removing AE2 recipes from KubeJS
\n* Removing recipes by output, type, or JSON match patterns (useful for large pack overhauls)<\/p>\n
***<\/p>\n
### \u2705 AE2 key wrappers (items\/fluids) exposed to JS<\/p>\n
Work with AE2-style item\/fluid keys in KubeJS-friendly objects.<\/p>\n
This makes it easier to:<\/p>\n
* Parse AE2 item\/fluid identifiers
\n* Compare keys (exact\/fuzzy matching)
\n* Read IDs\/mod IDs\/display names
\n* Format amounts similarly to AE2
\n* Serialize key data to JSON for logs, UIs, or debugging<\/p>\n
Perfect for scripts that need to understand AE2 storage\/crafting data in a clean way.<\/p>\n
***<\/p>\n
### \u2705 ME network (grid) monitoring APIs<\/p>\n
Inspect and track AE2 networks from scripts.<\/p>\n
The bridge can expose grid summaries and network state so you can build custom logic around:<\/p>\n
* Network online\/offline state
\n* Power storage and usage
\n* Controller\/channel state
\n* Node counts
\n* CPU counts
\n* Request\/crafting counts
\n* Storage summary information<\/p>\n
This is especially useful for:<\/p>\n
* Progression systems
\n* Custom quests
\n* Server diagnostics
\n* Automation triggers
\n* Admin tools and alerts<\/p>\n
***<\/p>\n
### \u2705 KubeJS events for AE2 activity (server-side)<\/p>\n
React to AE2 events directly in your scripts.<\/p>\n
Examples of event categories include:<\/p>\n
#### Network lifecycle \/ status<\/p>\n
* Network created \/ removed
\n* Network changed
\n* Network power state changes<\/p>\n
#### Storage tracking<\/p>\n
* Storage delta changes (item\/fluid amount changes)
\n* Threshold crossing events (custom watch triggers)<\/p>\n
#### Crafting lifecycle<\/p>\n
* Crafting requested
\n* Crafting job started\/completed\/stopped
\n* Stuck crafting detection events<\/p>\n
#### Player interaction \/ progression hooks<\/p>\n
* Terminal opened events
\n* Player milestone events (for tutorials\/quest progression)<\/p>\n
This enables highly dynamic pack logic such as:<\/p>\n
* Warning players when the ME system loses power
\n* Triggering quests when stock reaches a threshold
\n* Logging or notifying admins when a CPU gets stuck
\n* Unlocking guide chapters when players first interact with AE2 terminals<\/p>\n
***<\/p>\n
### \u2705 Storage threshold watches<\/p>\n
Register watches for specific AE2 items\/fluids (optionally scoped to a specific grid) and react when stored amounts cross a threshold.<\/p>\n
Great for:<\/p>\n
* Low-stock alerts
\n* Automated progression checks
\n* Soft automation triggers
\n* Pack health monitoring \/ dashboards<\/p>\n
***<\/p>\n
### \u2705 Optional scripted AE2 crafting request API (advanced)<\/p>\n
Plan and optionally submit AE2 crafting jobs through scripts.<\/p>\n
This can be used to:<\/p>\n
* Simulate\/plan an ME craft request
\n* Inspect required bytes and job details
\n* View missing\/used\/emitted items from a plan
\n* Submit a job (when valid requester context is provided)
\n* Track\/cancel submitted jobs<\/p>\n
This is a powerful feature for advanced packs that want **script-controlled AE2 automation logic**.<\/p>\n
> **Important:** The crafting request API is **disabled by default** in the server config for safety\/control. Pack devs must enable it manually.<\/p>\n
***<\/p>\n
### \u2705 AE2 device inspection helpers<\/p>\n
Inspect AE2-related block entities\/devices at positions and read useful state for scripts or admin tools.<\/p>\n
Depending on the device, this may include information like:<\/p>\n
* Class\/type name
\n* Position\/dimension
\n* Active \/ powered state
\n* Drive\/chest storage summary info
\n* Attached grid summary<\/p>\n
Useful for:<\/p>\n
* Debug commands
\n* Admin scripts
\n* Quest validation
\n* In-game diagnostic tools<\/p>\n
***<\/p>\n
### \u2705 Progression milestone hooks (AE2-aware)<\/p>\n
The bridge includes milestone-style hooks for player progression and tutorial flows.<\/p>\n
This makes it easy to build pack onboarding logic like:<\/p>\n
* First login milestone
\n* First AE2 craft milestone
\n* Controller crafted milestone
\n* Crafting terminal \/ molecular assembler milestones
\n* Other AE2 progression checkpoints<\/p>\n
Ideal for:<\/p>\n
* FTB Quests \/ custom questbooks
\n* In-game tutorial systems
\n* Unlock-based progression packs<\/p>\n
***<\/p>\n
### \u2705 Debug commands and data dumps<\/p>\n
Includes optional admin\/debug command support (server-side, permission-gated) for collecting stats, grid summaries, and diagnostic dumps.<\/p>\n
Excellent for:<\/p>\n
* Pack development
\n* Multiplayer troubleshooting
\n* Profiling AE2 behavior in scripted setups<\/p>\n
***<\/p>\n
## Why modpack developers might want this<\/p>\n
**Applied KJS** helps you build systems that would normally require writing a custom Java integration mod, such as:<\/p>\n
* AE2-aware progression scripting
\n* Dynamic recipe rebalancing
\n* Stock monitoring and alerts
\n* Scripted automation control
\n* Custom diagnostics dashboards
\n* Admin support tooling
\n* Event-driven gameplay tied to ME activity<\/p>\n
If you already use **KubeJS** heavily, this gives you a much deeper way to integrate **AE2** into your pack logic.<\/p>\n
***<\/p>\n
## Example use cases<\/p>\n
* **Quest gating:** Detect when a player first opens a terminal and unlock a tutorial chapter.
\n* **Automation safety:** Alert admins when an ME network loses power or a crafting CPU gets stuck.
\n* **Resource management:** Fire events when Certus Quartz stock drops below a threshold.
\n* **Recipe overhaul packs:** Replace\/adjust AE2 machine recipes entirely from KubeJS.
\n* **Progression packs:** Grant milestones when key AE2 components are crafted.<\/p>\n
***<\/p>\n
## Configuration (server-side)<\/p>\n
The bridge is designed to be configurable for pack\/server needs.
\nTypical options include toggles and limits for areas such as:<\/p>\n
* Network events
\n* Storage events
\n* Crafting events
\n* Terminal events
\n* Progression hooks
\n* Debug commands
\n* Craft request API
\n* Scan intervals \/ tracking limits
\n* Event spam protection \/ throttles
\n* Logging verbosity
\n* Dimension filters \/ allowlists<\/p>\n
> Recommended: Start with default settings, then enable advanced features (especially crafting request APIs) only when your scripts need them.<\/p>\n
***<\/p>\n

***<\/p>\n
## Notes for script authors<\/p>\n
This mod is primarily aimed at **server-side pack logic** and **modpack developer scripting workflows**.<\/p>\n
In general:<\/p>\n
* Use **startup scripts** to register reusable helpers\/constants (if desired)
\n* Use **server scripts** for AE2 events, monitoring, thresholds, and automation logic
\n* Use **client scripts** only if a specific client-facing integration is provided by the build\/version you are using<\/p>\n
***<\/p>\n

***<\/p>\n
## TL;DR<\/p>\n
**Applied KJS** turns AE2 into a scriptable system for KubeJS-powered modpacks \u2014 letting you build recipes, react to ME events, monitor grids, inspect devices, and (optionally) automate AE2 crafting flows with far less custom Java work.<\/p>\n","protected":false},"excerpt":{"rendered":"
